If a solution contains 28 g of potassium nitrate per 100 g, Ask an Expert

Academics

There are two chemicals used in this reaction, 1,6-hexadiamine (which is in a water solution) and adipoyl chloride (which is in a hexane solution). Think back to what you learned in this course about solutions and intermolecular forces. Why don't these to "mix" together (in other words, make a homogenous solution) when combined? Why do they separate into layers? What functional groups are the key players in this reaction? How so?
Explain, in as much detail as possible, why the nylon is only created at the INTERFACE between these two solutions.

Suppose we are dealing with potassium nitrate as opposed to the chemical in the video. If a solution contains 28 g of potassium nitrate per 100 g of water at 25 degrees Celsius, is the solution unsaturated, saturated, or supersaturated?
